Which of the following values of ' t ' may satisfy the condition 2 sin t = 
, t ∈ 
.
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a,c)
Let y = 2 sin t ⇒ y = 
(3y – 5) x2 – 2x (y – 1) – (y + 1) = 0
x ∈ R – 
∴ D ≥ 0 ⇒ y2 – y – 1 ≥ 0
∴ y ≥ 
or y ≤ 
⇒ sin t ≥ 
or ( k ) sin t ≤ 
∴ range of t is 
∪
